Content wise, I'm most looking forward to more Drifa and furthering the Family Matters Quest. I would really like to get another neck accessory that boosts magic, since there's nothing to replace losing the Amulet of Union that gives both Spell Power and Spell Penetration.
EDIT: After going through the new pregnancy content with Mai, I can't help but want an option to breed both of them. Especially if it allowed for a scene with all of the pregnant foxes, like what the orcs have. So could include Rindo if at that stage, or allow for repeated breeding.
I understand it will never be a thing and isn't allowed, but I'd love to read any fanfiction or unofficial content of the PC and Kinu together.
